We just returned from a nightmare experience with Allegiant Airlines too. We were to return home on Sunday. 3 hours before the flight, we got a call saying the flight was cancelled. They would book us on another flight Monday evening!!! If that didn't work for us, we should call the local airport and find out what airlines flew out of there. There was no helping us find a flight. We were not at home and had no computer access. We had to drive to another city (incurring a $100 drop off fee), pay for 3 tickets with another carrier ($470), had a 5 hour layover in Atlanta, finally got to Orlando International Airport (but our car was at Sanford so we had a $90 cab fair). If Allegiant has apologized and said they would refund our entire ticket price that would have almost covered the extra costs we incurred but they said they would only refund us the one way price. Thanks Allegiant, you have definitely lost a customer with us as well as with our friends and family that fly to Michigan.
